    drag-reducing behavior

    1. What does this "drag-reducing" mean? Does this "drag" mean by leader fish or by water? The translation goes "resistance", which seems to mean "resistance by water", but I doubt if it's by other fish.

    2. What does this "draft" mean? "floating around"?

    ex)Schooling also can serve as a drag-reducing behavior as individuals draft behind leading individuals, much as race car drivers do. Laboratory studies with fishes that instinctively school also indicate that if these fishes are isolated at an early age and prevented from...

    Keannu, you answer your own questions sometime. Reducing does not mean resistance. The translation is simply not correct. If the leading individuals cause the drag to be reduced, they don't cause the drag, do they?

    Re: drag-reducing behavior

    The analogy of the racing cars was a good one to help to explain "draft". In a car race, some drivers tend to sit directly behind another car, in its "slipstream". In this way, they conserve fuel because the car in front partly pulls them along. The same goes for fish, it seems. Individuals swim behind the leading individuals. The leading individuals do the hard work, swimming purely by their own effort and those behind, although also swimming, do not have to exert as much energy.

    Re: drag-reducing behavior

    Has "fishes" become an accepted plural of "fish"?

    Re: drag-reducing behavior

    It always was an accepted plural — especially when referring to different species of fish as in this context.

    It's always been an acceptable, but not often used, plural of "fish". Most dictionaries seem to give something along the lines of: "Plural: fish or fishes. The normal plural is fish, with fishes used to denote different species of fish".

    Edit: Posting at the same time as Rover but, as you can see, same info.

    Re: drag-reducing behavior

    I couldn't find the definition of "drag" used here in the dictionary, but according to your explanation, it seems to mean "to draw with force" and "such drawing force" reduces due to the guidance of the leader fish, right?
